How can private standard accelerate the development of organic production?
It is possible to use private standards to increase the speed in development of organic production in a wide range of areas and to do that on a solid scientific basis. KRAV has recently improved the standard performance in reducing climate impact of the production and the methodology from this work will be possible to use in several areas such as reduction of environmental impact, animal welfare and reduction of health risk for consumers
It is obvious, though, that we need to get more knowledge on how consumers value our extra requirements in the standard and their willingness to pay for these since this is of crucial importance to motivate the producers to accept more stringent standards
Bee Venom Induces Unfolded Protein Response in A172 Glioblastoma Cell Line
Background: Glioblastoma is a type of brain tumor with poor response to available therapies, and shows high rate of mortality. Despite remarkable advancements in our knowledge about cytogenetic and pathophysiologic features of glioblastoma, current treatment strategies are mainly based on cytotoxic drugs; however, these therapeutic approaches are facing progressive failure because of the resistant nature of glioblastomas. In the recent years, however, promising results have emerged owing to targeted therapies toward molecular pathways within cancerous cells. Unfolded Protein Response (UPR) is a remarkable signaling pathway that triggers both apoptosis and survival pathways within cells, and therefore induces UPR-related apoptotic pathways in cancer cells by ER stress inducers.
Objectives: Recently, the role of Bee venom (Bv), which contains powerful bioactive peptides, in inducing UPR-related apoptosis was revealed in cancer cell lines. Nevertheless, currently there are no reports of Bv potential ability in induction of UPR apoptotic routes in glioblastoma. The aim of current study was to evaluate possible role of Bee venome in inducing of UPR pathway within A172 glioblastoma cell line.
Materials and Methods: We treated the A172 glioblastoma cell line with different Bv doses, and assessed UPR-related genes expression by real-time Polymerase Chain Reaction (PCR).
Results: The IC50 of Bv for the studied cell line was 28 μg/mL. Furthermore, we observed that Bv can induce UPR target genes (Grp94 and Gadd153) over-expression through a dose-dependent mechanism.
Conclusions: Our results suggest the potential role of Bv as a therapeutic agent for glioblastomas.
